LANTERN.

To azz whom z't mag concern:

Be it known that I, CLAY H. Es'rns, a citi-' zen of the United States, residing at (lincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Lanterns, of which the following is a specification, reference being'had to the accompanying drawings.

This invention relates to certain improvements in lanterns, and has relation more particularly to a device of this general character of a type especially designed and Y adapted for use by railroad employees, and

it. is an object of the invention to provide anovel and improved lantern of this kind embodying a supplemental color screen removable into and out of position relative to the burner of the lantern so that the light raysemitted from the lantern maybe changed as to color. 7

A further object of the invention is to provide a novel and improved lantern of this type including a cylindrical base in which'the burner is arranged together with a supplemental color screen movable into or'out of the base and wherein said screen has coacti'ng therewith means for maintaining the burner inappli'ed position within the base.

The invention consists in the details of construction and in the combination and arrangement of my improved lanternwhereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

' The novel features of my invention will hereinafter be definitely claimed.

' In order that my invention may be the better understood, I will now proceed to describe the same with referenceto the ac; companying drawings, wherein Figure 1 is a view in elevation illustrating a lantern constructed in accordance with an embodiment'of my invention.

Fig. 2 is an enlarged fragmentary vertical sectional view taken through the lower portion of the lantern as herein included, certain of the parts being omitted.

Fig. 3. is'a'view in top plan of the oil.

reservoir as herein disclosed, and F1g. 4 is an enlarged top plan view of the supporting member'for the color screen.

in-gs, F denotes a lantern frame comprising vertically arranged standards 1 1n radial relation and formed of inwardly extending opposite extremities of the standards 1 are engaged with the rings 4. Coacting with the upper ring 4 in a well known manner is a cover C. w

Between the knees 2 and secured thereto is the base B preferably cylindrical in form and having its lower marginal portion defined by an inwardly directed flange 5 while the upper marginal portion ofthe base 13 is provided with the outwardlydirected' flanged shoulder 6 with which the globe or chimney G is engaged in a conventional manner.

7 denotes an oil reservoir insertible within the base B and of a maximum diameter less than the mean diameter of said base, and said reservoir is permanently fixed at its base with a disk D snugly fitting within the base Band resting upon the flange 5 whereby the reservoir'7 is properly supported within the base B. The marginal portion of the disk- Dis defined by an upstanding flange 8 while the extended portion of the disk D is'provided with the openings 9 to facilitate the requisite draft. To further facilitate the draft and to accommodate sufficient air to support combustion the side wall of the reservoir 7 is provided with longitudinally disposed corrugations 10 with the openings 9 adjacent the low points of the corrugations. v i 7 The reservoir 7 whenapplied has its upper end preferably terminating below the shoulder 6] and coacting with said upper end of the reservoir 7 is a burner 11 of a M denotes an annular member snugly fit ting within the base B and surrounding the reservoir 7 and the inner marginal portion of said member M is defined by the upstanding flange 12. The member M serves as a holder for the screen S of suitable transparent material and preferably red in color for a purpose which will be hereinafter more particularl'ydefined.

At preferably diametrically opposed points the member M has depending therethe member The opposite end portions of the slot 16 are offset laterally or provided with bayonet extensions, as indicated at 17, so that upon partial rotation of the member M said member may be locked in its lowermost position and whereby said member M is normally held against displacement when at the limit of its upward movement. 1

Suitably secured to the under surface of M is an end portion of a spiral spring '18 and which spring encircles the res ervoir 7 and engages the extended portion of the disk D. The spring 18is of an expansible type so that the same constantly urges the disk D toward the flange 5 of the base 13 so thatthe reservoir 7 is effectively maintained in applied position. However, the reservoir 7 can be readily removed after the member M and the spring 18 carried thereby has been withdrawn from applied position within the base B.

The spring 18 also operates to facilitate the elevation of the screen S and maintains the same in its elevated position.

When the screen S is elevated the same surrounds the flame of the burner 11 so that the light rays emitted from the lantern are colored.

While I have hereinbefore stated that the screen S is preferably red in color, it is to be understood that the screen may be of any selected color designed to exhibit a signal having a prescribed meaning.

When the screen S is at the limit of its downward movement the flame of the burner 11 is unobstiucted thereby so that the rays emitted from the lantern will be of the color of the globe or chimney G and which globe or chimney is preferably clear in order to produce what is known as a white light.

From the foregoing description, it is thought to be obvious that a lantern constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and'modiflcation without departing from the principles and spirit thereof, and for this reason I do not wash to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as herelnafter claimed.
